 The RTP temperature probe is designed for wide temperature range applications requiring
excellent chemical resistant properties and sensor submersion.All exposed parts
of the RTP are manufactured of either stainless steel, or Teflon based products,
resulting in excellent chemical resistance properties to acids, alkalis, ketones,
esters, aliphatics, aromatics, and outdoor exposure. The probe is constructed
of 304 Stainless Steel making it both durable and water resistant to 60 PSI.
The cable used on this sensor is Belden’s 7928A CAT 5, which uses Teflon based materials
for both the outer jacket and inner conductor insulation. This cable is particularly
suited for harsh environments, and offers excellent resistance to high and low temperatures,
oil, gasoline, and sunlight exposure. The RTP probe is manufactured using
a Teflon based heat shrink tubing that creates a water tight seal at the cable’s
point of entry into the tube. This results in a sensor that can be submerged
beyond the top of the steel probe.
For applications that do not require complete submersion or operation in harsh environments,
please refer to our STP (standard) temperature probe.The RTP temperature probe
is available with either a DS18S20 or a DS18B20 1-Wire temperature sensor embedded
into the probe. The RTP probe is manufactured using a special process that
insures the internal sensor is thermally coupled to the steel tube wall; this helps
insure rapid sensor response to changing conditions.
Our RTP sensor is supplied standard with Teflon CAT5 cable with stripped leads.
Pin outs are as follows:
- Common (GND): Blue / White
- 1-Wire Signal: Blue
- Ext. Power (Vdd): Orange
Please note that if you choose to operate the sensor in parasitically powered mode,
you must connect the Vdd and GND lines together, per the DS18x20 specifications.
When ordered with the optional RJ11 plug, we take the extra steps necessary during
the plug installation to properly configure the sensor for parasitically powered
operation.The RTP temperature probes are directly compatible with all Embedded
Data Systems and Dallas 1-Wire bus masters, our OneSix server software, and the
freely available TMEX drivers. For complete documentation on the embedded
DS18x20 sensors, please refer to manufacturer’s spec sheets available at
